Migration Cockpit Object custom modifications review before update in production system

[user5629]

Hi,

Trying to migrate data using Migration Cockpit staging table approach. We have had issues with objects containing custom fields. We added custom fields in development system and transported them to quality and then production. Objects containing custom fields have had short dump in quality LTMOM, in migration cockpit fiori app message "upload canceled; field definitions of upload file x.xml are out of date" or "column sterilization failed". Fields seem to be right looking at the tables. Now new project has been made, transported to production. In production fiori objects containing custom fields are giving error "This migration object contains custom modifications that must be reviewed before the update can be applied. In order to proceed, execute the following option from the toolbar of SAP S/4HANA Migration Object Modeler: Update Object.". But this can not be performed in production system object modeler. Is there a work around for this and how to proceed? The transport of copies doesn't seem to be option...

Thanks
